Be it known that l HENRY l5. KRAFT, a ClllZ-Gll of the United States ofr-imerica,

residing in Ridgevwiod, in the gen and State ot. New certain. new anduseful. 1m

Jersey,

county of Ber have invented provements in Water-Bottle Stoppers, ofwhich the follow ing is a specification.

This invention relates to water bottle stoppers, and aims to providecertain impro vements therein.

The invention is iiiarticularly directed to that type of water tliesocket member is provide lar extension, usually ccntr which 'is designedto permit bottle stopper in w hich d with a tillflb ally arranged.

the escape of air from the interior of the water bag, during'theoperation of titling the bag, Such stoppers have heretofore beenprovided, but

have been expensive to man cording to the present mven of this type .lSprovided which ufacture. Action a stopper is preferably constructed ofsheet metal throughout, that is to say, both the socket member and thestopper proper sheet metal. certain other hereinafter be more Referringto the the preferred form The invention drawing are constructed of drawnalso comprises improvements which will fully described.

Fig. 7 is a diametrical section of the let A indicatestopper, shown In Figure 6 is of the socket to which figure it will ofthe socket member is constructed preferably of a sheet metal cupproperly drawn socket member has connecte from fiat stock, and be ingprovided with 3. rolled thread D.

The d to it a vent tube E which may also be formed of sheet metal stockof seamless tubi ng or the like.

7 Serial No. 448,?S5.

As shown, the member nected to the bot-tom ber which is provided within'which the vent shown in the drawing, the tube is provided with flangesH. and I, whichv grip over the bottom F, thus. securely holding the tubein place. Asfbet'ore stated, the object of the tube E is/to provide a'vent for air while the bag is being tilled, and for this purpose thetube E is best extended a considerable distance above the upper edge ofthe socket member in order that in filling the water bottlei there willbe little liability of Water passing down through the tube.

The bottom of the socket member is pro vided with a passage or passagesbest seen in Figure Sand shown as three in number, which passages aredesigned to permit. the water to pass as rapidly as possible downintothe bag during the filling operation. These passages are preferablycut out of the cup which forms the socket member either during or afterthe drawing operation.

The socket member is also provided with a shoulder K extending aroundits interior and adapted to form a seat for the stopper which shouldermay be constructed during the drawing operation by reducing the diameterof the bottom, as shown.

The stopper B is best constructed of sheet metal and comprises abodyportion L which is threaded to engage the interior of thesocket memberand an imperforate' d0me shaped portion M, adapted to receive theprojecting end of the vent tube E, and also adapted to be used as ahandle for operating the device. The stopper is formed on its bottomwith an opening N, through which the vent tube E passes, there beingleft at the bottom of the stopper a marginal bearing face or shoulder P,which is engaged by the packing washer Q. The latter is of annularshape, being held in place by an annular plate R, which in turn issecured to the bottom of the stopper by rivetting a part of the bottomover the plate R, as shown at S.

The stopper is preferably formed of two cups drawn from sheet metal, thebody L being best provided with a flange at its top, as shown at T, anda dome-shaped extension Mbeing provided with an interlock ing flange U,as best seen inFigure 7.

tube is located. As

In order to provide a finger-hold for the stopper, the body M isprovided with a series of longitudinal ribs V which are formed in thedome during the drawing op eration.

By the construction thus described a cheap and eflicient stopper of theclass described is produced, and one which can be easily applied to andremoved from the socket.

While I have shown and described one form of the invention, it will beunderstood that I do not wish to be limited thereto, since variouschanges may be made therein without departing from the spirit of theinvention.

That I claim is 1. A water bottle closure comprising .a screw-threadedsocket member, a vent tube connected with said scrcw-threaded socketmember, a stopper adapted to seat in said socket member having anopening in its bottom through which said vent tube projects, and athetop of said stopper, and being hollow to receive said vent tube.

2. A water bottle closure comprising a screw-threaded socket member, avent tube connected with said screw-threaded socket member, a stopperadapted to seat in said socket member having an opening in its bottomthrough which said vent tube projects, and a dome-shaped extension fixedto the top of said stopper and being hollow to dome-shaped extensionfixed to I i'eceivessaid vent tube, ,andzsaid idome shaped extensionhaving a series of longitudinal ribs constituting a finger-hold.

3. A water bottle closure comprising a socket member formed of sheetmetal having an aperture in its bottom, and a vent tube connected tosaid bottom at said aperture, and said socket member having a seatarranged above said aperture and adapted to be engaged by a packing on astopper.

4. A water bottle closure comprising a socket member having portions ofits :bottom removed, and a vent tube connected with said bottom, saidvent tube being rivet-ted to the latter and extending above 'theupperend of the socket member, and a stopper comprising two sheet metal cups,one of which is screw-threaded to engage the socket member and the otherof which is a domeshaped extension hollowed on its interior to receivethe projecting-end of said vent tube.

5. A water bottle closure comprising a socket member formed of .Sheetmetal and having an aperturein its bottom, and a vent tube connected tosaid bottom at said aperture, the vent tube having a flange above saidbottom anda flange below said bottom, and said bottom having a secondaperture.

In witness whereof, I have hereunto signed my name.
